Unsupported operand type(s) for +: 'NoneType' and 'int'

I'm trying to upgrade my SQLITE db to POSTGRES. I run the following:

./sqlite2pg -e /srv/trac -p 'postgres://postgres:mypassword@localhost/trac?schema=myschema'

And receive the following error:

Traceback (most recent call last):
  File "./sqlite2pg", line 335, in <module>
  File "./sqlite2pg", line 331, in main
  File "./sqlite2pg", line 244, in Main

TypeError: unsupported operand type(s) for +: 'NoneType' and 'int'

Any ideas on this problem? It might not even be a bug ... but I'm not sure what exactly is the issue. Seems to perhaps be related to trac itself?...

I'm having exacly the same problem here Trac 0.11.1 from Debian repos (Lenny)

fyi, I'm having exactly the same problem when I try specify a different schema name. If I leave out the schema part, it works without a problem (Debian/Lenny).

I'm not sure if it really matters whether the trac tables are in schema 'tracschema' (or 'myschema', or whatever), or if they're in the public schema.

But, if you're using PostgreSQL 8+ and you want to have the tables in the correct schema, you can use sqlite2pg to migrate from sqlite into the postgres public schema and _then_ move it to your schema of choice.

1) run the conversion into the public schema

./sqlite2pg -e /srv/trac -p 'postgres://postgres:mypassword@localhost/trac'

2) create the schema

mach=> create schema myschema;

3) move all tables, one by one, into the new schema:

mach=>alter table table_one set schema myschema;

and repeat for all tables, indexes, and sequences

The Postgres 8 Docs can tell you more.
